>Zork created an Imzy community about debunking falsehoods, mostly political ones. It’s got 3,000 members and no trolls. This just seems like a way of saying "people who agree agree with me." In any controversial topic determing who is a troll at the margins of discussion is very difficult.
Say I post "black people are subhuman." I could be trolling (intentionally provoking emotional responses for the lulz) or that could be my actual honest to goodness opinion. You just don't know. There's also no polite way to express that opinion and that's the same for many, many opinions.
